EXCLUDING mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods. In these, ...

Refractory gold ores present significant challenges to conventional extraction methods. In these ores, gold is tightly encapsulated within sulphide minerals or locked by carbonaceous matter, thereby ...

An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold ...

At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool ...
